Constructor Details

IntervalMarker

public IntervalMarker(double start,
 double end)

Constructs an interval marker.

Parameters:

start - the start of the interval.

end - the end of the interval.

IntervalMarker

public IntervalMarker(double start,
 double end,
 Paint paint)

Creates a new interval marker with the specified range and fill paint. The outline paint and stroke default to null.

Parameters:

start - the lower bound of the interval.

end - the upper bound of the interval.

paint - the fill paint (null not permitted).

IntervalMarker

public IntervalMarker(double start,
 double end,
 Paint paint,
 Stroke stroke,
 Paint outlinePaint,
 Stroke outlineStroke,
 float alpha)

Constructs an interval marker.

Parameters:

start - the start of the interval.

end - the end of the interval.

paint - the paint (null not permitted).

stroke - the stroke (null not permitted).

outlinePaint - the outline paint.

outlineStroke - the outline stroke.

alpha - the alpha transparency.

Method Details

getStartValue

public double getStartValue()

Returns the start value for the interval.

Returns:

The start value.

setStartValue

public void setStartValue(double value)

Sets the start value for the marker and sends a MarkerChangeEvent to all registered listeners.

Parameters:

value - the value.

getEndValue

public double getEndValue()

Returns the end value for the interval.

Returns:

The end value.

setEndValue

public void setEndValue(double value)

Sets the end value for the marker and sends a MarkerChangeEvent to all registered listeners.

Parameters:

value - the value.

getGradientPaintTransformer

public GradientPaintTransformer getGradientPaintTransformer()

Returns the gradient paint transformer.

Returns:

The gradient paint transformer (possibly null).

setGradientPaintTransformer

public void setGradientPaintTransformer(GradientPaintTransformer transformer)

Sets the gradient paint transformer and sends a MarkerChangeEvent to all registered listeners.

Parameters:

transformer - the transformer (null permitted).

equals

public boolean equals(Object obj)

Tests the marker for equality with an arbitrary object.

Overrides:

equals in class Marker

Parameters:

obj - the object (null permitted).

Returns:

A boolean.

clone

public Object clone()
             throws CloneNotSupportedException

Returns a clone of the marker.
